Whether the video has been shot from a stationary (i.e. non-
moving) camera. When set to true, might improve detection
accuracy for moving objects. Should be used with
SHOT_AND_FRAME_MODE enabled.
The confidence threshold we perform filtering on the labels
from frame-level detection. If not set, it is set to 0.4 by
default. The valid range for this threshold is [0.1, 0.9]. Any
value set outside of this range will be clipped. Note: for
best results please follow the default threshold. We will
update the default threshold everytime when we release a new
model.
